Introduce docker_insecure_registries that is an array of host/port
combiniations of docker insecure registries. The default value will
be the previous parameter that were hardcoded, but now we can easily
override it in undercloud.conf.
Note: the feature is already supported for the containerized undercloud
but was only missing in instack-undercloud. This patch will be
backported.
